How Wearable Ring Sensors Are Tracking Sleep Apnea

In this episode of The Wearable Tech Podcast, Lucas and Luna explore how a new generation of smart rings is being used to screen for sleep apnea—a condition affecting an estimated 30 million Americans. Unlike bulky CPAP machines or hospital sleep studies, these lightweight rings use photoplethysmography (PPG) and accelerometers to detect breathing pauses overnight. The hosts discuss a recent study from the University of California, San Francisco, which found that an Oura ring prototype could identify moderate-to-severe sleep apnea with 90% accuracy. They also compare the approach to traditional diagnostic tools, examine the limitations of consumer-grade sensors, and consider whether this could lead to earlier intervention for millions of undiagnosed patients. The conversation stays grounded in the science: what the sensors actually measure, how they differ from medical-grade equipment, and what the FDA clearance process looks like for such devices. No hype, just the data behind the trend. #SmartRing #SleepApnea #WearableTech #HealthTech #PPG #OuraRing #UC San Francisco #SleepHealth #ContinuousMonitoring #FDA #MedicalDevice #Photoplethysmography #Accelerometer #Technology #Health #FexingoBusiness #BusinessPodcast #WearableTechPodcast Keep every episode free: buymeacoffee.com/fexingo
